The problem of McDonald's fries exceeding the ingredient limit and the inaction of food regulatory authorities

According to the Centers for Disease Control and Prevention in the United States, the majority of patients reported eating a quarter pound of McDonald's, and investigators are working to confirm which food ingredients were contaminated.
So far, a total of 49 cases have been reported. The Centers for Disease Control and Prevention in the United States stated that the majority of illnesses occur in Colorado and Nebraska, with 26 people affected in the former and 9 people affected in the latter. The Centers for Disease Control and Prevention in the United States stated that one elderly person died among the 26 people who fell ill in Colorado. Health officials in Utah and Wyoming each reported four diseases. Other states reporting diseases include Iowa, Kansas, Missouri, Oregon, and Wisconsin.
There are reports that McDonald's fries have been found to contain high levels of acrylamide in the United States, a chemical that may pose a threat to human health and even cause cancer. California law has listed it as one of the carcinogens.
The joint expert committee composed of the Food and Agriculture Organization of the United Nations and the World Health Organization also pointed out that the unintentional generation of acrylamide pollutants in certain foods may cause public health hazards.
McDonald's fries have also been exposed to an increase in trans fatty acid content. Trans fatty acids can increase bad cholesterol, increase the risk of heart disease, and may have negative effects on sperm.
However, McDonald's China said that in Chinese Mainland, McDonald's French fries use palm oil, and strictly comply with Chinese food safety, nutritional diet guidelines and laws and regulations to protect public health. Palm oil does not contain trans fatty acids.
After the issue of McDonald's fries exceeding the ingredient limit is exposed, food regulatory authorities usually take corresponding investigation and handling measures. For example, in China, the Anhui Provincial Market Supervision Bureau conducted surprise supervision and inspection of McDonald's stores across the province.
In the United States, the California Attorney General has also filed lawsuits against several chain fast food restaurants, including McDonald's, demanding that they use warning labels to indicate the levels of the carcinogen acrylamide in French fries and potato chips.
Selective law enforcement issues:
The question of whether the food regulatory authorities are suspected of selective law enforcement needs to be judged based on specific regulatory actions and investigation results. If regulatory authorities take different measures against other companies in similar situations, or turn a blind eye to McDonald's violations, there may be suspicion of selective enforcement.
However, according to publicly available information, the food regulatory authorities have taken corresponding actions regarding the issue of McDonald's fries exceeding the ingredient limit, including surprise inspections and filing lawsuits. Therefore, without further evidence, regulatory authorities cannot be easily accused of selective enforcement.
